Question

the wavelength is the distance between two repeating points on a wave. cilips the crests, or highest points of waves, are used to measure wavelength. a sound wave with a shorter wavelength has a higher pitch. a sound wave with a longer wavelength has a lower pitch. which sound wave has the shortest wavelength? wave 3 wave 2 wave 1

Explanation:

Step1: Understand wavelength definition

Wavelength is the distance between two repeating points on a wave.

Step2: Analyze wave 1

Count the number of wavelengths in the given space for wave 1.

Step3: Analyze wave 2

Count the number of wavelengths in the given space for wave 2.

Step4: Analyze wave 3

Count the number of wavelengths in the given space for wave 3.
Since wave 2 has the most number of wavelengths in the given space (more cycles mean shorter wavelength as wavelength = distance / number of cycles in that distance), wave 2 has the shortest wavelength.

Answer:

Wave 2
